H5N1 Strikes More Poultry Flocks in 3 States

By Lisa Schnirring

Federal officials today confirmed more H5N1 avian flu outbreaks in poultry in three states, with commercial farms in Missouri especially hard hit.

According to the latest updates from the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), the virus was confirmed at five farms in Missouri, all of them commercial facilities. 

Affected premises include a layer farm in Newton County that has nearly 1.15 million birds. Other producers include a turkey farm in Newton County, a broiler breeder farm in McDonald County, and three turkey farms in three different counties.

Over the past 30 days, the virus has led to the loss of nearly 4.3 million poultry in Missouri.

Outbreaks in California, Oregon

In other poultry developments, APHIS confirmed the virus on a commercial turkey farm in California's San Joaquin County that has 22,200 birds and in a backyard flock of 8 birds in Oregon's Klamath County.

APHIS testing also confirmed H5N1 in one more dairy cow herd, another in California, raising the national total to 957 and California's total to 736.

Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger


In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
